There's also US original vehicles that can be used for parts too, like this kooky Oh Blocker/ Red battlezord based car.
The titanus aspect is just because Titanus has a big gaping hole anything can fit in. That's why they used it to combine with the Kakuranger and Megaranger mechas back in the day.
