The artbook describes its sketch as "This is a sketch of when we were coming up with the last boss".
While it's not possible to determine how much progress in the programming department this colossus underwent, its unused texture segment found in the PS3 data sheets only lists two textures, meaning Evis' model was likely in a primitive state, possibly explaining why its in-game model wasn't shown off in the artbook.
Its sketch portrays the boss as a quadruped with several bone protrusions and slight humanoid proportions, however it's possible this design wasn't the final one. Using the representation of a human at the bottom of the sketch for scale, the boss was a tad higher than Quadratus.
No information on its strategy exists. The colossus was likely able to walk since a remnant of its path data is listed in the PS3 sheets and wasn't a stationary boss like Malus, but other than that nothing else is known.
- Since Buddha was renamed into Evis, many of the old Evis-related sheets were likely replaced, erasing previous information. The only sheets that are named Evis and are related to this colossus are the ones not used by Malus.
- The idol statue of Evis was a Valus copy until very late in development, unlike most other unused colossi. It was then replaced with the Buddha statue in the final version.
- Two songs from the soundtrack were likely to have been composed with the final boss in mind, before Malus took over. Gatekeeper of the Castle Ruins (M15P / Music 15 Pinch) and Final Battle (M15B / Music 15 Battle); as according to the files, they were meant to be played one after another in a fight. An example of songs meant to play one after another are Liberated Guardian (M13P) and A Despair-filled Farewell (M13B), which are mostly used for the smaller / faster Colossi.
