Throughout the series, I noticed that Ben never used some of the features of some aliens. And I think the majority are quite powerful and useful. I wanted to write them in a list.
AmpFibian: Mind reading, Intangibility
It makes upset that Ben never used AmpFibian’s mind-reading powers. It’s OP in my book.
The other ability is just used by Kevin in UA. Definitely useful ability.
Chromastone: Enchanted strength, Radiation absorbing and radiation immunity
Radiation absorbing ability is confirmed by Matt Wayne. It’s one of the abilities that Ben hasn't discovered yet.
And writers also said that Chromastone is stronger than Swampfire. We know how strong is Swampfire and It’s a shame we didn’t see any scene Chromastone doing a close-range fight.
Feedback: Space survivability
Wiki says Feedback is implied to be able to survive in the vacuum of space due to his species being born in a nebula. OK. Still useful.
Wildmutt: Fireable porcupine-like quills
I had NO IDEA Wildmutt has an ability like that. Idk when this ability confirmed but I’m curious what can it do.
Arctiguana: Underwater breathing, survivability in environments with sub-freezing temperatures
Underwater breathing is a surprising one. Actually I never realized he had gills lol. The other ability is kinda predictable.
Wildvine: Fertilizing ability (I don't know how to call that ability)
Growing vines, flowers, and fruits are maybe not useful in a fight but it can be useful casual. Maybe he can make unlimited food by it idk.
Clockwork: Time and dimension travel.
Clockwork can travel through both times and between different dimensions. It’s incredibly OP and I don’t think Ben can master that ability in a short time.
Atomix: Nuclear energy shields
OK.
Fasttrack: Arm-blades
Seriously, this dude needs some extra abilities. He is just a worse copy of XLR8. Not just one, he needs at least three new abilities I say.
Terraspin: Magic
I’m suspicious about that. Geochelone Aerios are capable to use magic from birth. But we’re talking about Ben. We saw Ultimate Ben used a shield before. But... eh... I don't want to talk about this ability too much because I don't want to misinform anyone (For now).
I don't know if that's all, there are probably also some features that I haven't written. If there are features I forgot to add, I would be happy if you write them below. I would like to learn your opinions about these features.
