Terra (Earth)
Terra's arena is lined with blocks usable with Uranus's Deep Digger.
Pattern Info
Terra has 3 actions
If Mega Man gets to the center 2 blocks of the screen, Terra will jump away and teleport. This loses time and should be avoided.
Terr can otherwise either shoot a small laser (The Spark Chaser), or a 3 ball shot that freezes Mega Man.
The Fight
Open the fight be charging the Mega Arm. Walk towards Terra and use a full charge shot. As soon as it hits, switch to Uranus.
You want to stand between blocks so Mega Man does not fall into the gap, and grab blocks from the left so you can continue to walk right while throwing blocks. Optimally, Terra never teleports and you don't have to jump.
