Energy = Force x Displacement x Cosine(theta)

I don't think they clash. Buccs are super saiyan energy, Xenons are battery energy. The skills are vastly different too.

Xenon is much more futuristic though, and he's got more of a blue neon glow type of theme, while buccs are more like a yellow/red/orange type. The charge used for Buccs is different from the one on Xenon. Also, the skills aren't very similar, because if you think about Mecha Purge and Air Whip, they're not similar to the skills of the Buccaneer line, like Bucc Blast or Landlubber Blast. Xenon has much more range than Buccs, because Xenon isn't strictly built to fight with fists like a bucc. They do have some ranged skills, but for the most part Xenon as a whole is similar in the idea of using energy, but has a whole different type of energy and uses it differently.

I dont agree, Amaranth generator is like buccaneers stimulating conversation. They both require a " charge" or " energy" to perform certain skills. They both have skills that charge the energy and naturally charge up the energy over time. If you simply forget about the visual animations and look at the mechanics it's actually pretty similar.

Not exactly, because Xenon is like a hybrid android, while Buccs just use energy and they use fists. Xenon on the other hand, uses his whip blade which is powered through mana but he also has the Surplus system and its like he's a humanoid robot that has upgraded features, which are basically his surplus buffs. They may have one or two similarities, but are very different overall.
