The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
For the character updating his suit, maybe Midseason Upgrade?
Don't know if the rest of what you mentioned can be troped, really. It's a plot summary, mostly.
Yep, an episode of a show can have dozens of tropes in play- a plot summary is meaningless without context for the aspects you think are tropeable.
If it's the last episode, you might be thinking of "Where Are They Now?" Epilogue - other than that, we can't help, because tropes are about meaning, not specific events.
Hello, once again. By the end of the Moldiver episode "Verity", Mirai and Mao are now balloon girls at a local theme park, while Misaki continues his deep space exploration mission. Meanwhile, Isabelle survives being tossed into the sun and reunites with Amagi/Machinegal and the other Machinegal Dolls on Earth. As Nozomu works on his version of the Moldiver suit, Hiroshi has just finished work on an updated version of the Mol unit.
Which trope fits this example?
