The Alpha Nonagon is supposedly a re-work of a removed Nonagon, with changed color and decreased size. It was supposedly added in late 2019. On September 27, 2019, it's health was nerfed. As of October 19, 2020, Led Zeppelin is no longer able to push these.
The Alpha Nonagon is a large light blue nonagon that is about as large as an Alpha Pentagon.
The Alpha Nonagon has 600 health and gives about 30000 experience upon destruction. It can only evolve from Alpha Octagon in the pentagon nest. Alpha Nonagon may evolve further into Alpha Decagon in the pentagon nest. It evolves uncommonly, and can commonly stay as Alpha Nonagon. Alpha Nonagon has higher resistance compared to Alpha Octagon, that's why it is noticeably harder to kill.
If you have reached a highest tier and have a high DPS, you can destroy Alpha Nonagon for its experience. As a lower tier tank, you will likely waste too much time trying to kill Alpha Nonagon. If you can destroy it easily, you should do so to level up. You can also use Alpha Nonagon in defensive purposes against Bots, if you are unable to defend by yourself. In this case, you can move behind Alpha Nonagon and trick bot into ramming Alpha Nonagon and taking massive damage. This will force the bot to retreat.
