Well in the other post I made, the one with Spooky, I showed off three you mentioned here, those being the Galaga, Galaxip, and Lady Pac Fighter. Here, I'll relink them.
That's what they look like, listed in that exact order. They all have an evolution as well which makes them look more complex, and the Lady Pac Fighter looks like Ms. Pac-Man from the Hanna Barbara cartoon in it's evolved state. I don't have a picture of the Galaga alien when it evolves yet, but it looks much the same. The other two are here.
The top two are Explosion Galaxip and Space Lady Pac Fighter. The bottom two are Brave Pac and Wizard Pac. Brave Pac is what you get for beating the game's main story the first time (which I've already done). I know he doesn't look like Sir Pac-A-Lot, but I honestly haven't seen anything that looks similar to him except a water-based knight which I don't have in my collection yet. Working on it. The Wizard Pac is called exactly that, but it doesn't look like the same character from Pac-Man World 2, nor even close. Just a typical wizard, really.
As for the rest, let's see. I've seen Anubis Rex and Killer Frog. I don't remember Anubis Rex very well, other than it looked like a Sphinx monument, but with an Anubis head. Killer Frog I've seen a couple times, and I definitely got excited seeing that one, as it's an obvious reference to Pac-Man World 2. I'll take a screenshot of both when I next see them.
As for Patra, she's the main image when you go to the shop, so she was easty to get a screenshot of.
I'll agree, I like her. She's super adorable, and I'd love it if she were more prominent in Pac-Man games. For Woofa, I haven't seen him at all yet. Maybe I just didn't recognize him, but again, if I see him, I'll screenshot it for you.
That's all I got for now. Also, sorry for the image spam, but if anyone takes issue with it, please say so and I'll start putting this stuff behind spoiler tags. I honestly don't mind at all.
