Gravattack just makes sense!
Astrodactyl and Diamondhead aren't that strong
-Diamondhead can be defeated by aliens like Echo Echo.
-Jetray's hyper space isn't that impressive compared to aliens like Portaler and Full Stop.
-Sucker Punch...Ben can beat Vilgax as almost any of this aliens so the same could be said about Sucker Punch.
-Gravattack can't control his Blackholes so wouldn't be that great.
-Astrodactyl can still be out powered by Ben's other aliens.
