Mako, Dive coaster at SeaWorld San Diego, United States

Emperor is a blue steel Dive Coaster built by Bolliger & Mabillard at SeaWorld San Diego. Its 153-foot lift hill leads to a 143-foot drop at 90 degrees, then a 123-foot Immelmann; the 734.9-metre track reaches 96.6 km/h. Each three-row train seats 18 riders. A blue sign reading "Mako" stands near the entrance, a remnant of the ride's first name.

SeaWorld San Diego announced the coaster on January 5, 2019, initially naming it Mako and planning a shark theme. Through the IAAPA it was renamed Emperor and rethemed to emperor penguins. Opening was pushed back by the COVID-19 pandemic, and SeaWorld set March 12, 2022 as the date.

The coaster was first announced in 2019 as "Mako", themed to sharks; through the IAAPA it was renamed Emperor and rethemed to emperor penguins. The name and theme refer to the penguin, not to any marine-conservation programme, and the queue sits south of the Penguin Encounter exhibit.

Emperor stands in the eastern part of SeaWorld San Diego, south of the Penguin Encounter exhibit; its queue and ride pavilion are reached by the pathways that normally lead to Journey to Atlantis. The train seats 18 riders in three rows of six, and the lift hill holds the car at the top for 3.5 to 4 seconds before the drop. The drop to the end of the ride lasts about 40 seconds.

The coaster was first announced in January 2019 as "Mako", themed to sharks; the name was later changed to Emperor and the theme switched to emperor penguins. The blue track and its vertical loop stand beside the Penguin Encounter exhibit, though no penguin habitat was built next to the ride.
