So I was sort of struggling to think of ideas for two events I suggested for the timeline which are Godzilla VS Kumonga and Kamacuras in 1969 and Godzilla VS Titanosaurus in 1975, but now I do think I have some ideas for those events in terms of where they could take place and how they are triggered, similar to descriptions done to other timeline ideas. If there is anything that could be improved with these event description, please let me know. With that said lets begin.
Godzilla VS Kumonga and Kamacuras in 1969
With this event, the battle could go as a battle royal between Godzilla, Kumonga and Kamacuras. Like maybe Godzilla appears in Bangkok, Thailand and is maybe summoned their by Deverich's Psionic Transmitter as part of an experiment. However, the Transmitter summons both Kumonga and Kamacuras to the city. Kamacuras arrives first and battles Godzilla. Kumonga who was originally chasing after Kamacuras arrives at the city and battles both Kamacuras and Kumonga, result in a battle royal between the three kaiju. Kamacuras defeated first when he Godzilla whacks him with his tail sending him into retreat. Kumonga launches his Vicious Threads at Godzilla but just like in Godzilla Final Wars Godzilla grabs the web thread and then proceeds to swing Kumonga around before letting go, send Kumonga flying into the distance.
OR
You could have Godzilla battle Kumonga and Kamacuras at different times in the same year, like Godzilla battles Kumonga at one point in the year and at some point Godzilla battles Kamacuras later on. Like maybe have Godzilla battle Kamacuras in Bangkok while Godzilla VS Kumonga could happen in New Guinea.
Godzilla VS Titanosaurus
With this battle in 1975, I think it would be a battle at sea, specifically in Pacific Ocean. Maybe the A.M.F are tracking down Godzilla with several ships. However as the ships are following Godzilla, one of the ships is dragged underwater and destroyed. Godzilla senses another kaiju near and soon Titanosaurus reveals himself and battles Godzilla. Godzilla begins to overpower Titanosaurus causing him to retreat into deeper water, Godzilla attempt to go after him but a missile barrage from the ships halts and Godzilla attacks the ships before he swims away.
If there's anything that could be improved with these idea let us know
