Ancient Rex SW145SD is an evolved version of Nightmare Rex SW145SD and belongs to Dino Agito.

Face Bolt - Rex[]

The Rex Face Bolt depicts one of the most well known dinosaurs, the Tyrannosaurus Rex. The design of Rex features its skull looking to the left while showing it's neck. It also features black, circular designs atop and below, the Tyrannosaurus Rex's skull. The design is outlined in black and is printed onto a translucent, light orange Face Bolt. The special addition of Nightmare Rex SW145SD that comes with the Beyblade Metal Masters DS game comes with a Metal Face Bolt with darker colored stickers that must be manually applied.

Energy Ring - Rex[]

Rex, as it's name states, is designed in the manner of the Tyrannosaurus Rex's head, neck, and tail on the Energy Ring's two sides, in which, they go into one another. Rex is translucent gold in color, with dark green highlights on the Tyrannosaurus Rex's neck and tails. Although Rex is decent in terms of Defense potential, as it has a pretty moderate weight, it has good Attack power as it is very jagged. The Metal Masters video game version of the Rex Energy Ring has green highlights around the top.

Fusion Wheel - Ancient[]

Spin Track - Switch 145[]

SW145 has three 'wings'. The gimmick of this Track is the ability to change from Attack to Defense by taking off the wings, and then putting them on the opposite way. The purpose of this is the ability to adapt to opponent Beys. In Attack mode, which is denoted by six grey claw-like stickers on the underside, the pointed ends of the Track are used for Smash Attack; meanwhile in Defense mode, shown by three triangular blue stickers, the edges are more rounded, in order to deflect opponent Beys. The modes are reversed for Left-Spin Beys. Testing has shown that SW145 is quite useful at attacking lower opponents in a similar fashion to H145 and R145. It is however outclassed for Defense purposes by GB145, BD145, and 230 due to the recoil it produces.

Performance Tip - Semi-Defense[]

SD
Main article: Performance Tip - Semi-Defense

Just as the Semi-Flat Bottom has a sharper tip than Flat, so too does Semi-Defense when compared to Defense. Before the release of SD, D was the absolute best Stamina Bottom available, but SD quickly took over the top spot, as is evidenced by the following tests:

SD is not able to wobble as much as D, so for defensive purposes, D should still be chosen over SD if you are trying to add some Stamina to your Defense custom. That being said, WD would be a better choice than D for that situation, and also arguably for Stamina as well because with the even wider tip. With it, it is allowed to circle the stadium in some situations when it is on a larger angle towards the end of a battle, thus outspinning D or SD based opponents. However, sometimes this does not happen, and SD easily knocks over the wobbling WD custom before it topples over itself.

It really comes down to personal preference when deciding whether to use SD or WD because they are so closely matched. For pure Stamina, it is impossible to tell which would win a given match, but WD would prepare you for more situations by being able to take hits better than SD. Test both and decide for yourself which one works best for what you are trying to do.
