Phobies riddle, find out who i am

I live deep, very deep somewhere
And im not very fast,
Mechs look at me with a glare
Thinking im not gonna last
Within a first look
I dont look useful compared to the rest
But im pretty tanky, dont get that mistook
I’ll be close to my team, so try your best

Which phobie am i?
(Im gonna say if youre correct in private)



1: fish live in water
2: poison
3: movant 1


Mechanical Phobies do not like him much
