Capcom's first two games, Vulgus and SonSon, were developed at the same time. There were only about 8 people working at the company at the same time, with 4 each working on either game.

Attachment It is often said that Mega Man was once used as Capcom's mascot in the 1980s, in a similar way to how Nintendo and Sega use Mario and Sonic respectively. Like many other statements of platforming characters being used as corporate mascots, this is untrue, as Mega Man has never been used to promote the wider Capcom brand of software outside of his own games or crossovers in which he appears. However, Capcom did have a mascot in the 1980s: the titular hero of Captain Commando - many earlier NES Capcom games were branded as part of the "Captain Commando Challenge Series", including licensed titles such as DuckTales, with game manuals having signed messages "written" by Captain Commando. Despite this, Captain Commando was never released on the NES.

Capcom's former community manager Seth Killian addressed Capcom's current lack of a mascot and Mega Man's use as an unofficial mascot on the Capcom-Unity forums in 2009:

"...we don't have an "official" mascot. We have a logo, that’s it.

As far as unofficial mascots go, however, yes, MM would definitely be that. I have actually heard someone discuss this, and I think the reasoning was something akin to Mega Man best embodying the spirit of the company.

So apparently in addition to making great games, Capcom is also here to save the planet from overthrow by evil robot masters (and according to recorded history so far, I'd say we're doing pretty well–2009 and still no overthrows)."

Seth Killian on Capcom's mascot:
According to former former Capcom artist Katsuya Akitomo, sometime around the late 90's/early 2000's, DC Comics approached Capcom to make a Justice League fighting game. Capcom asked for Mr. Akimoto's opinion and he rejected it. He rejected the idea for three reasons:

1. The power gap between DC characters was bigger compared to that of Marvel.

2. The 90's were a difficult time for the American comic book industry in general, DC in particular was "floundering" outside of the success of Batman.

3. Capcom's development process and the arcade business were in transition at the time, meaning that there were doubts as to whether investing in licensed games would have continued to be a smart investment. For instance, he cited how 2D games were becoming more and more expensive and how they were falling behind when it comes to 3D technologies.
The word "Capcom" was created from taking the first 3 letters from each word in "Capsule Computers" (from the subsidiary Japan Capsule Computer Co).
