Time to see if Lenom is a… um, what to call him? He's masculine, but would Gary Stu be the right term? What do you call an over-powered plant? Geranium Stu? But let's take it one step farther. Is Lenom an Anti-Sue? Anyways, let's check out.
Trait 1: Overall Beauty: MS/GS are generally described as having perfect bodies and a generally gorgeous appearance. While its not the worst MS/GS quality, it is unrealistic for someone to look that beautiful. MS, in most cases, have insanely large and seriously unrealistic breasts.
Verdict: I'm going off on a limb and say that green skin, bark sideburns, and leaves for hair isn't that attractive. On the other hand, he's got the build that you'd expect from a Dragonball martial artist.
Trait 2: Relation to a Canon Character: A lot of people consider having a character related to a canon character is a MS/GS quality. But, it depends on the context/ success/ immersion of your character. Brother/Sister/Cousins are fine, but avoid identical long lost twins because that is a HUGE MS/GS trait.
Verdict: Hmm, no real problem there. I guess the closest thing you could relate Lenom to would be Cell, given Lenom's ability to gain the traits of plant species he ingests and mix them together (i.e. Lenom eats a Senzu bean and some bamboo sprouts. Suddenly Senzu beans grow at a rate of 4 feet a day!)
Trait 3: Relationships with other characters: MS/GS get along with almost EVERYONE. Not everyone gets along with everyone. Its only natural that there are conflicting personalities. The characters shouldn't agree with everything your character says and does. It's realistic.
Verdict: ALERT! ANTI-STU QUALITY CONFIRMED. Lenom doesn't get along with anyone at first. He dislikes those who don't conduct photosynthesis for sustenance.
Trait 4: Spotlight: MS/GS have the spotlight on them. ALL. THE. TIME. There are other characters who deserve to have the spotlight as well! Even if the story is about your character, there has to be focus on other characters too. It's not all about the MS/GS.
Verdict: If anything, he's closer to an Anti-Stu. Sure, his special techniques are second to none. But with a base power level of 97,000, he'd have the most impact on a plot if he handed out Senzu Beans or if trained Yamcha, Mr. Only Wins Battles in DBZ Filler, than if he was on the front lines. So paradoxically have more of an impact OFFSCREEN than on screen. But that doesn't mean he'd be a pushover.
If it came to a Beam Struggle, no one is going to beat Lenom.
Trait 5: I'm Absolutely Flawless!: MS/GS are perfect in every possible way. The argument that they are a fictional character and should therefore be perfect is no excuse. Everything they do is flawless and they suffer no negative repercussion or consequence for their actions in any way, whatsoever.
Once again, that is unrealistic. People have flaws! Everyone has flaws and makes mistakes! And no, clumsiness is not a flaw, its a quirk. Flaws are what makes us learn from things like our own mistakes - or maybe other people's mistakes - and help us grow as individuals, something even fictional characters should emulate. Mistakes are part of growing up and developing. That's why it's called character development!
Verdict: Lenom makes plenty of mistakes. His mistake in using Stardust Fusillade for the first time blew up his whole solar system. He's sour and bitter and doesn't get friendly with people unless they put up with all of the crap he dishes out. He's a hermit and doesn't take an interest in things that don't have a direct impact in him.
Trait 6: 100% Chance of Success: The MS/GS is capable of executing everything to utmost perfection. Nobody is perfect. Failure happens, so play around with how it affects your character.
An example is Tex from Red vs. Blue. Tex, despite being skilled and powerful, is doomed to fail no matter how hard she tries. This makes her less of a MS. That, and that most of the other freelancers are almost as bad ass as her.
Verdict: No problem here. Lenom isn't going to win much fights at all if his opponents fight at a level of Super Saiyan II or above. But on the other hand, he isn't going to LOOSE many fights either.
Trait 7: Romance: Who loves MS/GS? EVERYONE! MS seem to attract the attention of EVERY male character, while GS attract EVERY female character, even if they have vastly different personalities and don't make sense being together. This is usually a wish fulfillment fantasy on the part of the author, typically with characters made to portray the author with the character the author likes most. A love triangle is also common in this.
How does the romance usually start? Well, it usually doesn't at all. The love interest(s) just SEE the MS/GS and BOOM! They fall in love instantly. No, not a little crush or just seeing a pretty girl. FULL adoration and love. No build up at all. And most times it occurs between two characters with no substance for actual relationships.
Like in real life, relationships take time to build. And they're not perfect. Friction/tension happens. Love is never instant.
Verdict: Once again, closer to an anti-sue. He's just not interested in relationships.
Trait 8: MS/GS is actually me: In most cases, a MS/GS is an embodiment of the author for "wish fulfillment" purposes. While basing your first character on your personality is ok, if you're not careful, the story might end up becoming a huge emotional diary entry about your life.
Verdict: Not the case. While I'm not very social, I don't actively try to drive people away like Lenom. I'd like to be a master martial artist, but what's the point if I had even less of a social life than I currently do?
Trait 9: The Power Level... ITS OVER 9000!: The character has all the power in the world and is far more powerful than the series main protagonist and sometimes all the main characters combined. Nothing can defeat them.
Verdict: Almost an Anti-Sue here. Having a base power level under Captian Ginyu isn't a drop in the bucket when the power of a Super Saiyan has become something kids not even ten years old obtain. But on the other hand, even Beerus couldn't afford to just let Lenom get a free hit in.
Geranium Stu: 0/9
