If you mean as a mount, then the first that comes to mind is this one.

There are also Lions in Waalx Animals & Creatures mod, but whether they can be used as a mount or companion i do not know for sure, although i doubt it. I use WAC but so far i have not seen a lion from WAC that could be used as a mount or Companion.

Thanks!
The idea was to find *something* that has a maned lion and then I could maybe make a personal CM partner beast out of it or just put it in the game as essential and use minionz! to minionise it
@ Oromish:
I think the vanilla rates are max x3, that means you're already using a mod that increases the sneak ranged damage rate.
You could look everywhere to find a mod that changes it back or you could make yourself a small one:

1. open the construction set,
2. only load oblivion.esm, no need to load any other esps or esms,
3. go to "gameplay" and select "settings"
4. then change the appropriate thingies
I'm quite a noodle myself when it comes to modding, but that should do the trick. Make sure you load the mod after any mods you have that change the damage rates.
I see that vanilla has them at x2 and x3 already. I'm not sure, but try replacing the number with the same number. The Construction set will detect it as "modified" and will overwrite whatever the other mod has done... I think... hmhm...
Am I right?
