Jon St. John
While being purely made for attack, E-106 Eta has the ability to split its head from its body to scare or strike opponents or simply attack them with its large fists. He can also create bombs who look like the character Bomb from Knuckles' Chaotix.
Battle with the Underground
When Robotnik sent the E-Series into battle Eta went down to a fake-out maneuver from Sonic and Tails.
Last ditch battle
Robotnik used the entire E-Series to kill the Underground, but the planned didn't work and Eta was part of the members of the team who didn't survive the EMP and was destroyed.
