Aight let's break this one down a little;
Wrath of Rakshasa was indeed filed for amusement ride purposes in May (Trademark #88571872).
A Rakshasa can be a few things. They're a humanoid boss in Elden Ring, or a tiger-headed fiend in Dungeons & Dragons. In Hindu mythology however, they're malevolent goblins/demons with the
ability to shape-shift into different animals. After all,
Looks Can Be Deceiving. Therefore I would expect that this trademark has a use.
In terms of teaser campaigns, Six Flags Great America has historically used Thursdays to continue dropping pieces of the puzzle for coaster projects like Maxx Force and Goliath, not that they've had the opportunity in awhile. That is exactly what's begun happening here.
The first posts of these campaigns have been red herrings; Maxx Force in particular began with heavy waterpark teasers before switching gears. The focus on Mardi Gras Hangover's pad has coupled with scrutiny that the adjacent Roaring Rapids is currently in a state of disrepair; the sign is down and there is much work needed to reopen it. However it also sits closest to a neighborhood that regularly complains about the noise and did so more after Maxx Force was built. No big coaster there, they could be misleading us about the Mardi Gras location.
In any case however the pieces are in place for Project 2025 to be of considerable note, so worth paying attention to indeed.
