In the same age group (circa) with Megatron and Optimus, not sure if younger or older than any of them. [We know that Megatron is just slightly older than Optimus canonically]
Younger than Pharma, ratchet and Drift, since ratchet and pharma are colleagues amd studied together are at least close in age. Drift is also close in age w them [if someone is able to link that thread you're welcome]
So yes. Tarn is the younger toxic gym-bro* of the couple.
