Soukyuu no Fafner: Dead Aggressor

Interested in the genre? Despite what people might say, mecha is a rich character focused genre with a variety of incredibly unique stories to tell. Here's a collection of shows with short, straight-to-the-point descriptions about each. Note that some of these were translated by fans, and aren't available officially/legally. A good amount of these are available on various streaming services, tho as for all well you might have to sail the high seas a bit. Disregard my personal scores, as its subjective at end of the day and you might like it. Also please don't dismiss some of these just because they're really old, they pretty much all hold up well even today. Check each out, and see what strikes your fancy. Any shows I personally haven't watch I got info on from fellow mecha friends of mine:

Debuted in SRW W - SRW L

These are the anime that appear in Super Robot Wars K for DS.

These are the anime that appear in Supa Robo Gakuen for DS. Yes, it's supposed to be spelled that way.
None of these anime feature any story whatsoever in this game, which saves me a lot of effort.

These are the anime that appear in Super Robot Wars UX for 3DS.

I think I will watch this one, but I noticed there's no one that makes interest stack for this one in order, then I will :)

if you watch gundam seed series, you will be noticed they have the same art style and also about mecha

so there's will be 69 episode in total to watch, good luck

Neon Genesis Evangelion is widely considered one of the most influential anime ever made, and a multitude of series were created to follow the leader, copying from its premise, characters, aesthetics, themes, and any combination of the previous. Here's some anime that can be considered to be EVA clones. Note: Some series that, in contrast, inspired EVA are included at the end.

An assorted stack of anime series involving alien characters on Earth or set in alien planets.

For anime with sequels, only the first seasons of each have been included in the stack. The genres include (but are not limited to) Comedy, Drama, Romance, and Action

Post-Evangelion anime boom seasonal anime that manages to maintain the high quality of the fewer, higher-quality shows before this anime boom.

Anime featuring mainly traditionally animated, hand drawn robots made between the year 2000 and 2009. As CGI started being used in anime in this period, some mecha series started shifting towards CGI robots, I think this list would be really helpful.

Original sci-fi anime, one entry per series/franchise.

Large variety of mecha shows for people trying to delve into every corner of the genre.

I had to filter out which ones were openings so the listing is different than the link above due to including endings and inserts.

The ranking takes into account the song more than the animation.
