Mind you, the above image is after he takes a spear made out of electricity that was the size of a 3-story house through his torso.
Long, Spoilerific explanation enclosed, don't read if you care about stories being spoiled.
[spoiler]The main character in the above motivator is Jack Rakkan. To put it lightly, the guy can give SS7 Gogeta a run for his money.
No, seriously, there are spoilers below. Big ones.
Fine. Don't say I didn't warn you.
The story introduces him by having him swing a sword the size of a skyscraper. One-handed.
He later creates an energy attack that misses the original target and blows up a nearby mountain in it's entirety. Let me repeat that: He blew up a mountain on accident. By missing with an attack.
When he fights Negi, the first attack he does is mistaken for a terrorist attack because every building within a city block feels an earthquake.
Major spoilers for the big fight below, don't read any further if you haven't gotten this far and care about the ending.
Negi gets the brilliant idea to use one of Jack's own punches to power a spell and try to take Jack out in one attack. This results in the spear mentioned above. The motivator is what happens after he survives that attack.[/spoiler]
