And this is the current sfw reference sheet of Megalo that was made in October 2021 with some small adjustments. The Eevee state is typically the result of devolution spray use before hand. Megalo started off as a mascot character of sorts but over time became a pokesona.

Personality wise, Megalo can vary depending on the situation but more likely than not pretty chill.
WARNING! Potion he use can potentially be unpredictable on exactly what will happen due to messing around with a lot of ingredients. Most of the time the general effect is know but the exact results can be a bit inconsistent.
