Persona Non Grata: Due to his mental instability Japan has made it so he can never return seeing him as a danger to everything. He doesn't really care, seeing his life in Angel Groove a major improvement over working for NERV.
If It Swims, It Flies: Somewhat Averted. Mecha Lord was actually in danger of drowning when facing the Kraken and it took quick thinking from the rangers to survive. Later, it gains flight thanks to the addition of Kaiba's Dragon Jet and Wing Gundam.
Benevolent Boss: To the people he freed from the mines, he freed them from slavery, gave them money to build Angel Groove, then let them live there, charges them almost no taxes, and gives all of the orphans free lifetime passes to Kaiba Land.
Fiction 500: On top of being richer than Scrooge McDuck, Kaiba owns Blackwater, the UN, Sony, Square Enix, Bioware, Bungie, and Nintendo.
Before the Rangers are deployed, this group of volunteers get sent out to the front to get horribly murdered by whatever it is that's attacking the city that week.A profile with more detailed info can be found here: http://thaeonblade.deviantart.com/gallery/#/d4iyysg
Ace Pilot: A good chunk of them, even though few have had a chance to show this.
The Atoner: Chris apparently defected and joined Zeon in the past.
Early-Installment Weirdness: In his first appearance he was like a Saturday Morning Cartoon Villain with petty schemes like stealing all of the air conditioning in Tokyo-3. But by his next appearance, he became a Knight of Cerebus and never looked back.
Kick the Dog: When he meets Shinji again in chapter 6, he says multiple speeches explaining that he sees Shinji as nothing more than a whiny waste of life that is a danger to everyone around him. Ouch.
Kick the Dog: On top of having a throne made out of dead puppies to make sure even the dumbest person gets he's evil he does this trope to both non-britannians and those of his children who disappoint him.
The Heavy: He causes the majority of the conflict regularly sending most of the Monster of the Week down to Earth to attack the Rangers, but its unknown what his current position is among the forces of evil.
Make My Monster Grow: He uses his Lance of Longinus to power up the monsters when the Mecha Rangers begin winning.
Harmless Villain: Even after going One-Winged Angel Cloverfield wasn't much of a threat. It pretty much just existed to show how badass the Mecha Rangers were after a rather lackluster first showing against Ramiel.
Alas, Poor Villain: Parodied. At first the narrative talks about how sad it is to watch such a majestic creature die...Until Shinji goes Renegade and decides to twist the knife and sadistically electrocute it as Dead Baby Comedy.
Breaking Speech: Enoch delivers a cold one to both the Rangers with Jet Alone as his mouthpiece and gives another one to Kaiba after the battle while he was looking at the recording of the previous conversation!
]]So far known to include Barricade, Blackout, Soundwave, and Scorponok, we still don't really know what their goal is...whatever it is, it won't be pretty.
All Your Base Are Belong to Us: Blackout's attack on the military base and the Decepticons infiltration of Angel Groove. Which has culminated into an all out attack while the City's defenses are scattered by the Godzilla Zillas]]
Ax-Crazy: Blackout just runs with it through and through.
Badass: Blackout earns his cred when he singlehandedly destroys Nerv US, while blind.
