Lion is a MSAgent character created by M_Yuasa from Japan. His apperance is, as his name suggests, a Lion.



Lion was first seen in February 2014, in Yuasa's MSAgent page in their website. In the page, there are remaining pictures of Lion (along with Cat1, also created by Yuasa), demonstrating their animations in the test pages.



It appears that it only works when you have old (or newer) versions of Internet Explorer.

Sadly, the chararacter was difficult to find a way to have it on any computers. But the acf is there when you inspect the Lion1 page.

Overall, the MSAgent itself is partially lost.

I have ACF files and ACA files for not only Cat and Lion, but also the scientist character. I cannot merge them unfortunately. But once I get home, I will share these files with you.

Alright.

Also, I do wish there is a program to convert ACF/ACA to ACS. Because like what Agentpedia said about trivia about ACF, the decompiler never got an official update for 8 years. Even the 1.5 Decompiler too.

Ok since you're home. You can share these files for me.

Okay, I checked it out (and I can't even open ACA files). It would've been cool if he was recreated tho.

For Modern PCs with AgentPatch, I can rename ACF to ACS because ACF didn't work with Agent View in Modern PCs with AgentPatch.
