Buzzshock

Buzzshock is a green Megawhatt from Nosedeen Quasar.

Abilities
He has the natural abilities that Megawhatts has. He can pass through any electrical source with amazing speed, and he has the ability to manipulate electricity. Buzzshock has a sonic-scream. He can also duplicate and fly. Although not too much has been revealed, this little alien can really shock and its species has a dangerous sense of humor. All powers were seen in the episode Tourist Trap. Unlike regular Megawhatts, Buzzshock's electricity is color green.

Ultimate Alien
It is confirmed by Dwayne McDuffie that not every aliens in the opening will appear in Ben 10: Ultimate Alien, so it is still unknown if Ben will unlock him in this series. The green spot on his head is now grey, causing him to resemble a battery. He does not have the bulbs in his arms as he did in Ben 10,000'.
