All the little girls are crazy super-natural characters with super-powers; from an animation perspective, they're a lot more interesting. Annie summons meteors, rides on stars,
does Pretty Cure fighting moves and uses her rabbit to channel the power of the universe. Visually, it's not even a contest: Beowulf is by far the most stock and vanilla character in the entire cast.
There's nothing supernatural about Minette and people are going nuts over her just because she's cute - her gimmick/excuse to fight is that somehow customers would follow her everywhere other than the restaurant where she works to give her tips and stuff, including the goddamn skullgirl layer, which breaks suspension of disbelief even in a setting as flexible as this one...
As for gameplay, I don't see how a stock grappler character sounds fun at all. Even a Sol clone would be more entertaining.
All of his "inspirations" are grapplers; why wouldn't I expect a grappler?
Other than the monster fighting part, that sounds no different from Zangief.
A wreslting character can have throws without having his whole game revolving around landing that one big throw that makes it all worthwhile - while someone slow and heavy like Zangief may be the reference for a lot of people, there have been plenty of agile and mobile characters with special throws as important parts of their arsenal, while retaining many other viable attack options, KoF for one has something of a history with it.
As for Beowulf's appeal as a comparetively regular guy, frankly, it's something the game needs - to me the fact that SG is a cast of weirdos stands out more than the fact that it'll be all-female until Big Band comes along, and someone like Filia as the postergirl just emphasizes that, which is why I defend that Parasoul should have that role instead.
IMO, a good protagonist should set the done for the game or be the "plain" center around which the surrounding weirdness can be judged:
- in Street Fighter, you have Ryu as a mostly plain Karate guy with a few small distinguishing characteristics and some moves that defy physics, which set the tone for the early days of the game when most characters represented some martial art or stereotype with the odd bit of flashiness, and it worked out perfectly
- for Fatal Fury, you had Terry, who gave off an urban yet colorful vibe that is pervasive across the entire series
- in Guilty Gear, which is another series with a cast of weirdos, you have Sol, whoose look is far from something you're likely to find in good ol' Earth Prime, but feels plain in looks and gameplay compared to most of the cast in his game, yet he has quite some significance in its central conflicts
Well, this sort of turned into my "Parasoul would be a better protagonist" rant, but basically, SG could use something resembling "normal" as a breather for the weirdness, and I welcome Beowulf to deliver it.
